Email validation that keeps your sender score alive

SalesMarketingEmailAnalyticsDeveloperAutomation

CampaignKit is a real-time email validation and list-cleaning service that scores every address 0–10, catches disposable inboxes, flags catch-all servers, and runs batch validation jobs on your full contact database. Connect it to Actionist and your agents can validate a single address before a cold email goes out, submit 50,000-address lists for overnight scrubbing, pull quality scores to gate campaign sends, and fire automatic cleanup workflows the moment a spam trap is detected — all without anyone opening the CampaignKit dashboard.

Bounce-proof the inbox before support replies

When a customer emails support from an address that previously bounced, your agent validates the address in real time, scores its quality, and routes the outcome before a rep wastes time composing a reply. Invalid addresses get a Slack alert with the bounce reason; valid addresses get a follow-up calendar event blocked so the rep can respond at the right time — zero bounced support replies, zero wasted rep hours.

FAQs

Questions about CampaignKit + Actionist

Is CampaignKit a campaign-sending tool or just an email validator?

CampaignKit is a validation-only service — it verifies whether email addresses are real, deliverable inboxes and scores their quality, but it does not send emails itself. Think of it as the quality gate your agent runs before handing a list to your email platform of choice. Once connected, your agents can validate single addresses in real time or submit entire lists for batch cleaning.

How does the MCP connection work, and what permissions does it request?

The MCP connection uses a permissioned OAuth handshake between Actionist and your CampaignKit account. During setup you authorise Actionist to read and write validation jobs, retrieve results, and access account balance data. No credentials are stored in Actionist — the MCP server manages the token exchange. You can revoke access at any time from your CampaignKit account settings under Connected Apps.

What does the 0–10 email quality score actually measure?

The quality score combines multiple deliverability signals: whether the domain's MX records resolve, whether the specific mailbox exists at the SMTP level, whether the domain has a history of spam complaints, and whether the address pattern matches known disposable or role-based address formats. A score of 8–10 means high confidence in deliverability; 5–7 is borderline and worth a manual check; below 5 means skip it — the bounce risk outweighs the send.

What happens when CampaignKit identifies a catch-all server?

A catch-all server accepts every incoming email regardless of whether the specific mailbox exists, which means validation cannot confirm deliverability at the address level — only at the domain level. CampaignKit returns a 'catch-all' status and a quality score that reflects domain reputation rather than mailbox certainty. Your agent can be configured to route catch-all addresses to a manual-review segment rather than the main send list, balancing reach against bounce risk.

How do batch validation jobs work, and how long do they take?

You submit a list by either uploading a CSV/TXT file or passing addresses directly. CampaignKit queues the job and processes addresses asynchronously — typical throughput is 50,000 addresses in 10–30 minutes depending on server load. Your agent polls the job status endpoint until the job completes, then retrieves results or downloads the cleaned list. Credits are consumed only for addresses actually processed, so a cancelled job stops charging at the point of cancellation.

How are credits consumed, and can I avoid running out mid-job?

Each email address validated or found consumes one credit. Batch jobs reserve credits at submission time if your balance is sufficient; if the balance is too low, the job is rejected before it starts. Your agent can check account balance before submitting a large job and abort early if credits are insufficient. Configure the Credit balance low webhook trigger to receive an alert when your balance drops below a threshold you set — your agent can then pause queued jobs and notify the person responsible for top-ups.

How do I stop the agent from re-validating the same addresses every week?

Use the List validation jobs action to check whether a job was already run against a given list in the past N days before submitting a new one. Your agent can compare the list fingerprint or the job creation timestamp to avoid duplicate credit consumption. Alternatively, store validated results in a Google Sheet with a 'last validated' timestamp and have the agent skip any address that was validated within your freshness window — typically 30–90 days for stable B2B addresses.

What types of disposable email addresses does CampaignKit detect?

CampaignKit maintains a continuously updated list of known disposable and temporary email domains — covering services like Mailinator, Guerrilla Mail, 10-minute-mail, and thousands of lesser-known throwaway providers. It also detects pattern-based disposable addresses on otherwise legitimate domains. When an address is flagged as disposable, your agent can block it at the point of form submission, suppress it from the send list, or route it to a re-engagement flow that asks the contact to confirm a permanent address.
